Friction Challenge
We started off our Forces IDL by looking at friction. We discussed what friction is and when it can be useful. We were then set a challenge to investigate friction. We were being employed by Hot Wheels to help them sort a problem with their new loop the loop track. We needed to work out which material would be best to help the car build up speed to get round the loop, and then find a material which would help the car stop at the end of the track. Here are some photos of us conducting our investigation:
